FAQ

Question?
What is the difference between the Icn and Icu breaking capacity ratings on the A9N21174?

Icn (rated short-circuit breaking capacity) is defined by the IEC/EN 60898-1 standard for residential applications and is 4500A for this device. Icu (ultimate short-circuit breaking capacity) is defined by IEC/EN 60947-2 for industrial applications and is higher at 6kA, indicating its robustness in more demanding environments.

No, this is a 1P+N (single pole + neutral) device designed specifically for single-phase circuits that include a neutral wire. Both the phase and neutral must be connected for it to function correctly and provide proper circuit isolation. The overcurrent protection is only on the phase pole.

The 'C' refers to the tripping curve of the breaker. A C-curve is a general-purpose curve suitable for most applications, like resistive and inductive loads (e.g., lighting, sockets). It is designed to trip magnetically between 5 and 10 times the rated current (In), which helps avoid nuisance tripping from motor start-up inrush currents while still providing effective protection.
